Abstract: PURPOSE:To easily manufacture low pressure mercury vapor discharge lamps by heating an economical mercury alloy containing low melting point metal materials in set conditions to evaporate a part of mercury and depositing the alloy on a glass plate face, which is a discharge end part. CONSTITUTION:An alloy which is solid at room temperature for handling easiness and quantitativity at the time of sealing in a lamp and becomes a liquid at the temperature lower than the softening point of the glass is used as a mercury alloy and it is preferable for the alloy to have sufficiently lower vapor pressure than mercury at the working temperature of a fluorescent lamp. At the time of heating, the melting point Tma deg.C of the mercury alloy, the minimum value Tmm deg.C of the melting points of metals of the alloy except mercury, the average temperature T deg.C of the glass, and heating period (t) second are needed to satisfy the following relation; 5<=t, A-Bt<=T<=(A+100- Bt) or Tmm wherein A=Tmm, B=(Tmm-Tma)/20. In above mentioned conditions, heating is carried out easily from the outside of the glass by a burner or a furnace. For example, a zinc mercury alloy with the 50:50wt. % ratio of Zn to Hg is used and heating is carried out under the conditions in which A=420, B=5, and 5<=t<=30.

Title: Regenerating method of condensed water desalting equipment using ammonia
Inventor: KATOU TOSHIO
IPC: B01J49/00
Filed: 1979-01-16
Abstract: PURPOSE: To shorten aqueous ammonia circulation time and prevent the leakage of Na ions, by performing back wash with water again before circulation of aqueous ammonia in a method of regenerating cation and anion exchange mixed resins.  
     CONSTITUTION: Cation and anion exchange mixed resins used in the water column of ammonia-type condensed water desalting equipment are transferred into a regeneration column. The exchange resins are back-washed in water first so the resins are almost divided into a cation and an anion exchange resins. The upper layer of the anion exchange resin is regenerated by an alkali regenerating agent and back-washed again in water so that both the resins are completely separated from each other. Aqueous ammonia is then caused to flow only downward through the resins. The lower layer of the cation exchange resin is thereafter regenerated by an acid regenerating agent. As a result, the circulation time of the aqueous ammonia is shortened and the leakage of sodium ions into processed water is reduced.

Filed: 1990-01-09
Abstract: PURPOSE:To shorten measuring time by altering a sequence of measurement when counters for the number of deficiencies in measuring items are judged to reach foxed values. CONSTITUTION:First, the number of deficiencies in a test item A measured by a measuring means 3 is counted with a counter 11 and a judging means 21 judges whether counts thereof reach a fixed value or not. When the counts reach the fixed value, the test item A is put first in the sequence of measurement and subsequently, the counter 11 is cleared. Then, when counts of a counter 12 are decided to reach a certain value, an alteration 22 is made to put a test item B first in the sequence of measurement. Thereafter, counts of counters 13 and 14 are judged for test items sequentially. Thus, the test items indicating a higher deficiency rate are put first in the sequence of measurement thereby enabling the shortening of measuring time.
